Hi, everyone!
I’ve been working on my trills for a few weeks now by practicing trills.
My practice regime is this: trilling with each finger combination for a bar or two of 16th notes at 80 bpm across all strings between the 1st and the 15th fret.
However, I can’t supinate my fretting hand forearm at 90 degrees angle, only up to 45 degrees, and I feel like that has a negative effect on the development my finger dexterity and speed. I play with my guitar strap high and mimicking the classical position and that helps to an extent, but sometimes the fingers holding down one of the frets (mostly my ring and middle finger) exert tons of pressure even though I pay attention to a light touch on the strings.
My question is: Is efficient practice for fast trills a matter of building endurance at a lower tempo before gradually progressing to higher speeds or a relaxed Bruce Lee-type technique using the twitch reflexes and working on accuracy rather then raw speed?
Any advice with regard to this technique and legato in general would be helpful!
